TeSys protection components - Trinet

Selection guide according
to required electrical
durability (continued)
TeSys contactors
For utilisation category AC-3
Use in category AC-3 (Ue ≤ 440 V)
Control of 3-phase
asynchronous motors
with breaking whilst
running.
The current broken (Ic)
in category AC-3 is
equal to the rated
operational current (Ie)
of the motor.
Millions of operating cycles
Current broken in A
Operational power in kW-50 Hz
Example
Asynchronous motor with P = 132 kW -Ue = 380 V-Ie = 245 A - Ic = Ie = 245 A
or asynchronous motor with P = 132 kW -Ue = 415 V-Ie = 240 A - Ic = Ie = 240 A
1.5 million operating cycles required.
The above selection curves show the contactor rating needed: LC1-F330.
(1) The dotted lines are only applicable to contactors LC1-BL.
Use in category AC-3 (Ue =660/690 V)
Control of 3-phase
asynchronous motors
with breaking whilst
running.
The current broken (Ic)
in category AC-3 is
equal to the rated
operational current (Ie)
of the motor.
Millions of operating cycles
Current broken in A
Example
Asynchronous motor with P = 132 kW - Ue = 660 V - Ie = 140 A - Ic = Ie = 140 A
1.5 million operating cycles required.
The above selection curves show the contactor rating needed: LC1-F330.
